Research profile

The research interests of the Department of Pharmacology and Brain Biostructure are centered on neurodevelopmental models of schizophrenia. Specifically, our investigations are aimed at identifying the neural substrates underlying behavioral deficits typical for schizophrenia and the discovery of novel potential targets for antipsychotic substances. Another important aspect of our research involves environmental factors (early life stress, enriched environment) that influence brain development and its susceptibility to mental disorders such as anxiety, schizophrenia, cognitive deficits and depression.

Research methods

Behavioral: neurodevelopmental models of schizophrenia, experimental models of stress – maternal separation in the postnatal period, fear conditioning paradigm – the acquisition, retention and extinction of memory traces, sensory motor gating paradigm, novel object recognition test, delayed alternation test, social interaction test, food-preference test, latent inhibition test.

Immunohistochemistry and neuroanatomy: brain tissue staining for identification of specific proteins and their colocalization – microscopic techniques based on light microscopy, fluorescence and laser confocal microscopy, stereological techniques. Stereotactic and iontophoretic techniques of retrograde marker delivery. Methods to assess adult brain neurogenesis.

Biochemistry and molecular biology: protein expression: Western blot, ELISA, protein macroarrays; Real-Time Quantitative Reverse Transcription, chromatin precipitation.
Electrophysiology: in vitro measurements of long-term synaptic potentiation and depression.
